Dizziness is a common symptom, and recent research shows that physical activity and specific treatment of vertigo and dizziness are effective. The management of dizzy patients requires assessment and, when appropriate, treatment by a physiotherapist. We have therefore studied how general practitioners (GPs) handle patients with vertigo and dizziness, to find out whether treatment follows current r

We investigate tunable hole quantum dots defined by surface gating Ge/Si core-shell nanowire heterostructures. In single level Coulomb-blockade transport measurements at low temperatures spin doublets are found, which become sequentially filled by holes. Magnetotransport measurements allow us to extract a g factor g;{*} approximately 2 close to the value of a free spin-1/2 particle in the case of

Seedlings of Pinus sylvestris L. were grown in Plexiglas(R) observation chambers in limed (CaCO3, pH 5.0 and 5.9) and untreated (pH 4.1) peat. The seedlings were either colonized by the mycorrhizal fungus Paxillus involutus (Batsch: Fr.) Fr. Or were non-mycorrhizal. After 18 wk in the observation chambers, N-15-labelled organic nitrogen, as lyophilized and ground mycelium of Suillus variegatus (Sw

The soil acidification model SAFE was modified to calculate historical changes in geochemistry and runoff since the last glaciation ended at the Lake Gårdsjön F1 catchment 12 000 B.P. Changes in runoff pH and ANC, soil weathering rate, soil mineralogy, soil texture and base saturation was also calculated. The changes in mineralogy compared favorable to data. Modeled historic weathering rates were

Future adaptation to changes in the environment depends on the existence of additive genetic variances within populations. Recently, considerable attention has also been given to the non-additive component, which plays an important role in inbreeding depression and bottleneck situations. In this study, I used data from a North Carolina II crossing experiment, analysed with restricted maximum-likel

The adsorption and the hydrolytic action of purified cellulases of Trichoderma reesei, namely, cellobiohydrolase I (CBH I), endoglucanase II (EG II), and their core proteins, on steam-pretreated willow were compared. The two enzymes differed clearly in their adsorption and hydrolytic behavior. CBH I required the cellulose-binding domain (CBD) for efficient adsorption and hydrolysis, whereas EG II

Haemophilia B, an X-linked recessive bleeding disorder characterized by lack or deficiency of factor IX, has been shown to be caused by any of a variety of DNA abnormalities (partial or total deletions, nonsense or missense mutations). Since in most countries carrier detection is based on factor IX coagulant activity (FIX:C) assay, this study was designed to determine whether carriers' FIX:C value

Data from ice cores suggest that Late-glacial and early Holocene atmospheric CO2 variations were rather conservative, the most important change being a gradual Younger Dryas increase. By contrast, palaeo-CO2 records based on the inverse relationship between CO2 Partial pressure and stomatal frequency of terrestrial plant leaves reflect a more dynamic CO2 evolution, including an abrupt decrease at

In order to estimate the detention effect (storage and peak flow attenuation) of a sedum green-roof, a comparison between the response of an impervious roof (runoff coefficient C = 1) and a green-roof has been carried out. Precipitation and runoff data from several controlled experiments (with wet initial conditions, i.e. approximately at field capacity) on a sedum green-roof were used for the ana

The aim of this study was to examine biochemical changes in cell wall carbohydrates and extensin proteins during long-term storage of carrots (Daucus carota L. cv. Nerac). During the storage period of 6 months, cell wall fractions were isolated from the carrot at various times for carbohydrate and protein analysis. Signs of extensin cross-linking and its concomitant insolubilisation in the cell wa

A retrospective cohort study was performed in Sweden to evaluate the possibility that an individual symptom or constellation of illness symptoms related to silicone occurs in women after breast implant surgery. A random sample (n = 2500) of all women in the Swedish national implant registry who underwent breast augmentation surgery with alloplastic breast implants during the years 1965 through 199

Hormonal cancers such as breast and prostate cancer arise from steroid hormone-regulated tissues. In addition to breast and prostate cancer hormonal regulation has also a role in endometrial, ovarian, testis and thyroid carcinomas. The effects of estrogens, androgens and progestagens on tumor growth are largely mediated by paracrine and autocrine target molecules which include growth factors and g

We present a case of primary seminal vesicle carcinoma detected at transurethral resection. The clinical presentation, radiologic findings, and pathologic features of these tumors are reviewed. Grossly, seminal vesicle carcinoma is poorly circumscribed and solid or solid/cystic and may be misinterpreted as an abscess or hemorrhage on radiologic examination. Although a definitive diagnosis often ca
